Be it known that I, Wmnnm Wanton Geezer, citizen of the United Stet residin at Brooklyn in the county of rigs and to of New forlr, have invented certain \w and usefullmprovenients in Fuel- Mixture Hen sndVnpo Devices, of i which the folliifi'ing'ie a spool cation. This invention relates to an' improved fuel mixture heating and veporizin dance of the general character illustrate in my ending epielicntion' for a-similer inventionled N ove 24', 1920. Serial No 426,798. The salient object of the present invention resides in the provision of a device employ.- ing bodies for heating the fuel mixture,

wherein heat will be supplied to the bullies Th by a heatin medium flowing around the bullies iind w rein heat will further be sup? lied to the bofllesfhy aehestin medium owing centrelly' throuihihe es.

A further obyect of he invention is to provide a device employing, in con unction with the features previously noted, a resistor for heating the bnflles.-

A still further object of the invention is provide a device wherein the core about which the resistor is wound will also provide a conductor for a. heating medium and wherein thebailies will also be assembled around said core.

And the invention has no still further object to provide a device which may be employed in connection with internnl oombustion engines of practically any design.

Other and incidental} objects will appear hereinafter.

device being us interposed between the carburetor and he manifold. Leading from the exhaust mzmifold 13 to the nipple 17 of the ecket 16 of the device, is a pipe 26 for con uctin'gexhaust gases from the engine into the jacket. However, when preferred, a liquid heating medium may be directed intothe jacket. v the shell 15 is va Arranged axielly of tubular heat conducting core which, is

formed of mating sections 27 nnd 28 respectively, having threaded connection at their meeting ends. The section 27 is formed with an elbow 29 extendin to the wall of the shell opposite the nipple 17 while the section 28 is provided with a.

ioo

similar elbow 80 extending'to the well of I the shell 0 posits the ni pic 18, and threaded in shell are con ling sl'ehves 31 fitting into'tho elbows, the el ws beil'lg preferably counter-bored to accommodate said sleeves so that the sleeves will provide closed joints between the sleeves and the elbows.

The sleeve '84 is; rovided .so as to obviate the possibility 0 any of thefuel mixture finding its way between the baffles to come i'n contact with the-resistanceelement 33 thus preventing'fouling' of said, element. orngedonthe shell at its inner side is a plurality of'smt-- ibly'spaced redial stop .11! 42 engaged by thebnfiie 36, these lu 'be xiig provided-for win th i': imter ends, said sleeves are notched es'enuglliy b'ut. removably fitting the bindingpost 85 and 36,133

lmfiles 5i 4 in, theehell and i115 terposed between the baflle 85 and the herd 21 at the adjacent end of the shell is a spacmg ring 43 coast ng with the'finnge 23 of said head. This rm'g in, of course, epertured to accommodate the elbow 29 of the section 27 of the core so that the bafiles will be clam ed between said ring and the lugs &2. xtending throu h' the web 19 connectmg the shell and jam: at is -a vent ipe 4.4 threaded at its inner end portion t rough theecllar 39. of the section 2.8 of the core, through the hub of the haflle 36 and through the elee've 34, this pipe establishing oomn'mmcution between the interior ofthe sleeve and ,the outer eir. r 1

- Formed on the coller 89 of the section 28 of the core is uni ple 45 and-extending freely through said threaded through thewe fldoonnec ting' the jacket and shell .and flan ed at its 0lfl/G.I Blld to overlie the -jackel:.- attending through this tube is a binding post 47'; projecting'mto the sleeve 34; and insulating the post with rspect'to'the tube as relies with respect to the sleeve-and the lmbofthe 'bitiile 36, is a. dielectric bushng 48. At its inner end,

arries a. not 49 oa'ted with in suitable insulating material or otherwise insulated from the"sloeve 34 end'adjacent arts and, as will now be observed one end of the resistance element 33 is suitably enogag'ed with this nut for conneeting the resistance element withthe binding post as previous!)' intimetedl At its outer end r tion the binding post carries suitable fives ers and threaded upon the po'st'is a binding nut 50 engaging with a. circuit fire 5L1 ing from any apgro'ved source of electrical ene Prefera 1y a rheostat, as conventionally illustrated at 52, isinterposed in the circuit. Formed on the elbow 30 oftlie eection 28 of the core .it the base of the nipple 45, is a boss 53 haying a T-shaped passage 54 therein osening through oppositesides of the boss an fitting through the web 20 is a pipe 55 threaded at its inner end intothe boss to communicate with said 'assager Inter osed in the pipe is a suitable valve 56.

s willnow be readily understood in view 'ofthe preceding de'scri tion, \hen the aircuit through thetwireo 1 is do I, the resistance element 83 will .be heated for mg the sleeve 34; and consequently the bnf fies so that the fuel mixture, as it is drawn through the ehell 15 from :the carburetor 14,- will be heated and vaporized by said 'baflles. Accordingly the engine may be readily started Hence, when the baffles are so heated, the electric our-rent to the resistance element may be cut Oil and the engine started, whereupon heated exhaust gases 1n the exhaust manifold '13: will [low through the ipe 26 withi n the jacket 16 around the shel for heating theshell as well as increasing the temperature of the bailies so that heatfuel mixture flowing through the shell. will be heated in corresponding increased degree. Coincidentl the heated exhaust gases will also flow t rough the core of the resistance element for heating said core as well as'heatin the baflles centrally. The temperature; 0 the baflles will thus be furtherraised for oorrespondingl heating the fuel mixture with increased e ciency. The pipe 55 is provided .in order that, when esired, a dccarbonizing fluid may be introduced into the shell to be taken up by tho fuel mixture and thence drawn into the engine cylinders for cleaning the combustion chambers of the cylinders. I accordmgly provide a highly ellicient construction for the per so forth and while I have shown and escribcd the referred embodimeat of the invention sti as may be r elved, various minor changes or mod' ca tions may be made therein, while, of course, the s ecific shape of the device may, in the insta lation of the invention, be changed to meet the varying requirements of practical use.
